I want to reinfoce a plaster board wall by cutting out a square section with a plaster wall saw, apply a piece of plywood in the cavity between the plaster and the proper wall (about 2 inches of empty space).

I then want to put the plaster wall section back on and reseal it as if nothing was done.

How do I re-apply the section and what materials and tools do I need for a pro finish?

FYI - I'm doing this so I can hang my LCD tv. There is one stud (metal) going down the centre of where I want to mount the TV, but is obviously too week to take the load.

  1. hiya i have been in the plasterboard trade for 8 years now and i have done many of the patch ups that you are asking bout and they way that Dave C has told you is perfect.


  2. mark and cut out ur section, install timber to  inside wall (s***w if timber frame,compressed anchors if conc.)either side of stud.finish your timber(thick as you can)to the inside edge of the p.board,s***w your p.board back on the timber with drywall screws,you can buy appropriate bonding for the gap,tape to cover  joints and filler to fill and sand flush the edges. s***w only at edges so tape will cover.take your time an old handsaw is an easy clean way to cut plasterboard start each side by working the saws point up and down til u get through.be sure to use specific brackets for the job.


  3. You can carefully cut the plasterboard out with a utility knife and a saw - try not to damage the skim coat - and put aside. Fit the plywood - I would use two inch blocks where the brackets are going, but whatever. Then refit plasterboard with adhesive over the blocks, if you cant reinforce the joint with wooden strips behind so much the better. Infill cut lines with cellulose filler and finish smooth.  I have done this several times (mainly for running in additional cabling) and if careful you can't see the join.
